Viewing Version Definitions

At last some improvements: you can now view the set of versions in an MVD. These can be grouped hierarchically to any depth, and each step in the hierarchy can be named:

The Version List

Viewing one version of the Sibylline Gospel

The text illustrated here is the moderately complex Sibylline Gospel – an apocalyptic prediction about what will happen at the end of the world. Nicoletta has recorded 36 versions, some of which are shown in the expandable list above. Getting this text right necessitated the fixing of a number of bugs in the NMerge package, but all seems to be well now. To build the document I used the MvdTool, which is a commandline version of NMerge. It does many of the same things as the wiki, but without the user-friendly interface.

Next step is to add twin-view, which will allow the user to instantly see highlighted differences between any two versions in an MVD. The edit version of this view will probably display a HTML rendering on the left and an editable window on the right, updated every few seconds, or at the press of an 'update' button.
